This room is unnamed on screen. Its designation as the "Locker Room", either fully capitalized consistently or with the two initials capitalized in subsequent uses of the phrase, comes from the revised final draft script of "Fight or Flight" and the final draft scripts of "Sleeping Dogs", "Minefield", "A Night in Sickbay", "The Communicator", "The Catwalk", "The Crossing", "Anomaly", "Damage", "The Forgotten", and "Observer Effect". The final draft script of "Bounty" differed from these formatting methods, instead formatting it "locker room".
The locker room briefly appears in "Bounty", though it was not referenced in the scripted version of that scene. Instead, the final draft script of "Bounty" referred to the locker room at a point in the episode when it doesn't actually appear, detailing a journey Sub-CommanderT'Pol takes from inside the decon chamber to a corridor outside it as passing through the locker room. In the final edit of the installment, T'Pol heads through a different door of the decon chamber, which leads straight to the corridor.
